Popular touring e-bike with comfortable Fun Ride geometry in a lightweight aluminium frame - for added comfort and control. This is a new addition to the 2022 e-bike range. Powering the e-bike is the powerful Sport Drive mid-motor, which offers a high quality yet very affordable alternative to other mid-motors on the market, giving us a very pleasant and smooth ride. Maximum power output of 500 watts and an efficiency of more than 80%. The motor is equipped with a torsion sensor that helps depending on how hard we pedal.

Power is provided by a reliable 504 Wh frame battery that lasts for long trips. The model is built on 29" wheels for fast trail riding and all-day touring. Just to the left hand side is the SPORT DRIVE control unit, which shows for example the battery level or the current speed. Comfort is taken care of by a suspension fork with 100 mm travel and safe stopping is the job of the powerful Shimano disc brakes. The e-bike is equipped with full touring gear such as a rack, mudguards, kickstand, lights and lock. In terms of additional comfort, you'll appreciate the WTB Nineline 29x2.25" tires with reflective stripe.
